QR Code Component Completed with HTML and CSS Flexbox

I was fumbly with Github and the deployment of my solution. It's clear that I need to work on learning Git, hah. I have a few resources that I plan to delve into, but any suggestions on specific content would be great.

I'm always interested in feedback regarding accessibility best practices-- If you happen to take a look, and you spot a potential issue or something that can be cleaned up, I'd love to hear your insight.

Any other feedback is appreciated. I'm here to learn by doing, and I've got a lot of work to do. Thank you so much!!

Update: I added the lang and dir attributes to the HTML tag. This was to fix the accessibility error caught by the solution report.
